The relationship between how much of a good is available and how much buyers want, which determines its market price.
The spike in energy prices was a textbook case of supply and demand moving out of balance.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
